Screenshot Journal was created “with iOS designers and developers in mind,” but it is useful for anyone who takes a lot of screenshots. For instance — and I’ll pick a completely random example here — tech bloggers.

The (universal) app does one thing: gather all the screenshots from your camera roll and organize them for your viewing pleasure.

On of the funnest* things you can do with off-camera flash is to modify the light. This might mean squirting it through a “snoot” (some kind of tube or cone which focuses the light into a tight beam), reflecting it from a colored, uh, reflector, or firing it through a giant soft-box.

Or you can use a grid spot, an excellent tool for pointing your light at one single spot, far away, with a sharp fall-off into shadows at the edges. Sound expensive? It can be, unless you steal some drinking straws from your local fast food emporium and follow along with this how-to.

Arqball Spin is a curious mix of hardware and software, with a very niche but very cool purpose: to create interactive 3-D photos. By combining an iOS app with a hardware turntable, Arqball is able to “film” a spinning object and then render it as a touchable 3-D model which can be spun using your fingers.

645 Pro bills itself as an app which will turn your iPhone into a DSLR. At first glance, it seems like this has been achieved by mimicking the buttons and LCD panel of a modern SLR, and to an extent that’s true. But the real meat here is under the hood: 645 Pro shoots uncompressed JPEGs and TIFFs, and gives the closest that we’re likely to see to RAW images from the iPhone’s camera.

With Wi-Fi inside, Samsung's new NX cameras are almost as good as cellphones

Speaking of Wi-Fi connected cameras, Samsung’s entire new range of NX mirrorless cameras has Wi-Fi inside. This is an improvement on Nikon’s new D3200 – also announced today – which requires an awkward dongle to do the same trick.

There are three new models, the NX20 and NX210, which replace last-year’s NX10 and NX200. There is also the brand-new entry level NX1000. All share the same 20MP sensor as the old NX200.
